The background image shows confocal micrographs of fruitfly egg chambers (ovarioles). The structures in green are called ring canals, and are visualized using a GFP-tagged protein trap allele of the endogenous Fimbrin gene. Fimbrin is an actin crosslinking protein that helps form the ring canals that form bridges between the nurse cells and the developing oocyte. Cell nuclei are stained in blue. The image represents a 3D stack of multiple optical sections that have been projected in 2D for optimal viewing.
